Bringing a Dog Into the United States: CDC and USDA APHIS Rules Explained

Bringing a dog into the United States requires clearing rules set mainly by the U.S. Centers for Disease Control and Prevention (CDC), plus narrower requirements from the United States Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS). Since August 1, 2024, every dog entering or returning to the U.S. must have a CDC Dog Import Form receipt, be at least 6 months old, appear healthy, and carry a microchip; dogs arriving from a CDC-designated high-risk country for dog rabies face additional vaccination and paperwork rules (CDC, 2024).

There is no single federal "pet passport" for dogs entering the U.S. Instead, the requirements depend on where the dog has been in the past six months and where it was vaccinated. This guide walks through the current CDC and USDA APHIS rules, the forms you need, and how the process differs from other pet travel systems people often confuse it with, such as the EU pet passport.

Who Regulates Dog Imports Into the U.S.: CDC vs. USDA APHIS

The CDC holds primary jurisdiction over dog imports because its mission is preventing the reintroduction of dog-maintained rabies into the United States. As USDA APHIS states plainly on its own pet travel page, "APHIS Veterinary Services has requirements only if your dog is coming from a country affected by foot-and-mouth disease (FMD) or screwworm" (USDA APHIS, 2026).

In practice, this means most dog owners will deal almost entirely with CDC rules. USDA APHIS involvement is limited to:

• Foot-and-mouth disease (FMD) countries: the dog's fur and bedding must be free of excessive dirt, hay, or straw, and the dog should be bathed on arrival and kept separated from livestock for five days. No paperwork is required for this step (USDA APHIS, 2026).
• Screwworm-affected countries: the dog needs certification from an official government veterinarian confirming it was inspected for screwworm within 5 days before shipment and is free of infection, or was quarantined and treated. In Mexico, an authorized clinical veterinarian may issue this certificate on the government veterinarian's behalf (USDA APHIS, 2026).
• Dogs used for livestock handling imported from most countries outside Canada, Mexico, and parts of Central America and the West Indies must show no evidence of tapeworm infection (USDA APHIS, 2026).
• Commercial dogs imported for resale or adoption fall under separate APHIS Animal Care regulations, not the standard pet-travel rules (USDA APHIS, 2026).

U.S. Customs and Border Protection (CBP) also checks documentation at the port of entry, and individual states or territories can layer on their own entry requirements, so confirm rules for your destination state as well (USDA APHIS, 2026).

Step-by-Step: How to Bring a Dog Into the United States

1. Check your dog's travel history. Review the CDC's list of countries considered high-risk for dog rabies to see if your dog has been in any of them in the 6 months before U.S. entry (CDC, 2026).
2. Confirm your dog is at least 6 months old. Dogs younger than 6 months are not eligible for entry under current CDC rules (CDC, 2024).
3. Make sure your dog has a microchip. Any brand is accepted as long as it is detectable with a universal scanner; if it can't be scanned on arrival, the dog can be denied entry and returned to its country of departure (CDC, 2024).
4. Complete the CDC Dog Import Form online for each dog you are bringing in, using the importer's, owner's, or shipper's information, and double-check the email address before submitting (CDC, 2026).
5. Save the receipt. The confirmation email produces a receipt you can print or show on your phone. It's valid for six months and multiple entries provided the country of departure doesn't change (CDC, 2024).
6. If traveling by air, show the receipt to the airline before boarding, and keep it available to show CBP when the dog arrives in the U.S. (CDC, 2026).
7. If your dog visited a high-risk country in the past 6 months, follow the additional vaccination, titer, and documentation steps below before you travel.
8. Check destination-state rules and any USDA APHIS requirements tied to foot-and-mouth disease or screwworm-affected countries of origin (USDA APHIS, 2026).

Low-Risk vs. High-Risk Countries: What Changes

Whether a dog needs extra paperwork depends on whether it has spent time, in the 6 months before arrival, only in countries the CDC classifies as rabies-free or low-risk, or whether it has visited a country on the CDC's high-risk list.

The CDC's list of high-risk countries for dog rabies changes as disease status changes, so check the official list close to your travel date rather than relying on a saved copy. The CDC's dog importation pages were last confirmed as updated in 2026, and the agency directs travelers to its Dog Importation Navigator tool to determine which category applies to a specific trip (CDC, 2026).

The CDC Dog Import Form: What It Is and Isn't

The CDC Dog Import Form is an online form, not a physical passport. It must be completed once per dog by the person importing the animal, and it generates an email receipt that functions as the required entry document (CDC, 2026). On February 5, 2026, the CDC updated the online form system's look and formatting; the agency was explicit that "there are no changes to importation requirements" tied to that update (CDC, 2026).

This form replaced a more document-heavy process for dogs from low-risk countries starting August 1, 2024, when the CDC's new rule took effect. The agency said the change aimed to "protect the health of U.S. communities and animals" while cutting paperwork for lower-risk trips, based on feedback from the public, industry partners, and other countries (CDC, 2024).

How This Differs From the EU Pet Passport and Other Travel Documents

Travelers researching "bringing a dog into the United States" often also encounter the EU pet passport, a booklet-style document used for pets moving within the European Union and under the EU's pet travel regulation. That is a separate system, issued by an authorized veterinarian in an EU member state, and it is not accepted or required by the CDC or USDA APHIS for entry into the U.S. Airlines also set their own pet carriage rules (crate size, cabin vs. cargo, breed restrictions) that are independent of, and in addition to, federal import requirements — always confirm directly with your airline before booking.

It's also worth distinguishing government import clearance from private identification tools. Animal Passport's digital livestock passport uses phone-based muzzle biometrics — capturing a nose print, similar to a human fingerprint, that is unique to each animal — along with an estimated age from a dental photo and a body condition score from a side-profile photo. That system was used during livestock flood rescue efforts in Pakistan in August 2025 to help farmers reclaim animals after paper ear tags were lost in floodwater. It is a biometric identity record for livestock owners, not a government-issued travel document, and it does not replace the CDC Dog Import Form, USDA APHIS certificates, or any other official U.S. entry paperwork for dogs.

Common Mistakes to Avoid

• Assuming a rabies vaccine record alone is enough. Every dog still needs the CDC Dog Import Form receipt, even from a rabies-free country (CDC, 2024).
• Booking a land-border crossing for a foreign-vaccinated dog from a high-risk country. That group can only enter through an airport with a CDC-registered animal care facility (CDC, 2024).
• Traveling with a puppy under 6 months. These dogs do not meet the minimum age requirement for entry (CDC, 2024).
• Ignoring state-level rules. Federal clearance from CDC and USDA APHIS doesn't override additional requirements some U.S. states or territories impose (USDA APHIS, 2026).
• Confusing this process with the EU pet passport or assuming a private digital ID product satisfies federal entry rules. Only CDC and USDA APHIS documents meet U.S. import requirements.

Frequently Asked Questions

Do I need a CDC Dog Import Form even if my dog has all its vaccines?

Yes. Every dog entering or returning to the U.S. needs a CDC Dog Import Form receipt regardless of vaccination status; it is a separate requirement from proof of rabies vaccination (CDC, 2024).

How old does a dog have to be to enter the United States?

A dog must be at least 6 months old to enter the U.S. under current CDC requirements (CDC, 2024).

Is a microchip required to bring a dog into the U.S.?

Yes, all dogs need a microchip that can be read by a universal scanner; dogs whose chips can't be scanned on arrival may be denied entry and returned to their country of departure (CDC, 2024).

What happens if my dog visited a high-risk rabies country in the last 6 months?

The dog needs rabies vaccination plus additional documentation — either a Certification of U.S.-Issued Rabies Vaccination or a Certification of Foreign Rabies Vaccination and Microchip, depending on where it was vaccinated — and unvaccinated dogs from high-risk countries are not permitted entry at all (CDC, 2024).

Can I bring a dog from a high-risk country through a land border crossing?

No, not if the dog was vaccinated outside the U.S. Foreign-vaccinated dogs from high-risk countries may only enter through a U.S. airport with a CDC-registered animal care facility (CDC, 2024).

Does the CDC Dog Import Form cover multiple trips?

Yes. The receipt is valid for six months and covers multiple entries as long as the dog's country of departure does not change during that period (CDC, 2024).

Is the EU pet passport valid for entering the United States?

No. The EU pet passport is an EU-specific document for pet travel within the European Union; it is not recognized as a substitute for the CDC Dog Import Form or USDA APHIS requirements when entering the U.S.

Does USDA APHIS require a separate certificate for every dog import?

No. USDA APHIS requirements only apply if the dog is coming from a country affected by foot-and-mouth disease or screwworm; most dog owners will only need to satisfy CDC requirements (USDA APHIS, 2026).

Rules change as country rabies-risk status changes. As of September 2026, always verify current requirements directly on the CDC's dog importation pages and the USDA APHIS pet travel site before finalizing travel plans, since this article reflects the CDC rule that took effect August 1, 2024, and later system updates through 2026.
